ANS Stream Team

Happy #EarthDay! 🌎 Be sure to enjoy and advocate for your local #waterways today and every day!

Throwback to last season on this #FieldWorkFriday! Counting down the days till we're back in the water doing DRWI #research on the #DelawareRiver watershed

#tbt when we found this beautiful Northern Red-bellied Cooter during fieldwork 😍This threatened #turtle has lost a lot of habitat but loved the slow-moving creek we were sampling that day!

The exhibit also features footage of Patrick Center scientists like Dave Keller and @TanyaDapkey Make site you stop by to learn more about what we do!

Ocean Bound exhibit teaches us how we impact the ocean, what a watershed is & how we can be more mindful of how our actions can impact the quality of water. Dr Keller talked to our summer campers about the fish he studies & the new exhibit. @AcadNatSci

Lin Perez, EDS lead, speaks about “How to get to the River” art installation as part of a celebration for Water Year @AcadNatSci @AcadNatSciPR

The goal of the project is to create an inventory of freshwater snail species, like the invasive Chinese mystery snail Tanya is holding (or rather, the snail that Patrick Center director Roland Wall is lovingly looking at)! Also pictured is Andrew Weber an NPS ecologist.

Last week, a team of ANS scientists went site scouting with the National Park Service @NatlParkService along the Upper Delaware River. The project requires travel from site to site via canoe and kayak, a new experience for many of the team members.

Have you explored the Delaware River? She's beautiful this time of year. #naturelovers #getoutside Photo credit: @tanyadapkey

The loggers are secured to large rocks in the stream. Melissa mixes a special underwater epoxy to affix a bracket that will keep the logger in place... which is really important considering how our local streams can experience high flows during storm events!

At some sites, we've also deployed temperature loggers, which record the water temp automatically at set intervals. These data provide a more complete long-term temperature profile for the stream and define seasonal trends.

This handheld meter measures water temp, pH, conductivity (to gauge the amount of metals and ions in the water) and dissolved oxygen. This gives us a snapshot of basic water quality conditions on site and can help inform the info we get from the sample we take back to the lab.

We're in the field today measuring seasonal fall conditions of some Philly area streams! We look at physical characteristics like stream temperature and flow, and take a water sample back to the lab to look at nutrients and suspended solids. It's a beautiful day to be out!
